"P cPPICE I ADAM LEROY SCHWAB, OF NEW PHILADELPHIA, OHIO Incom-FEEDER CLAMP VAnn SHOULDER SUPPORT 'v Appnbation med spin 13,

VWhen employing the usual ingot feeders or hot tops, there is severe danger of break- Y age under expansion, with consequent danger of portions'of the broken Afee'derffalli'ng into the ingot mold and producing an inferior ingot. To prevent such occurrences in caseV thel feeder should crack, it is now customary to wrap suitable wire around said feeder prior l to the pouring operation, but itis the aim of l the present invention to provide a new and ,improved clamp to. surround the feeder, Y which clamp will overcome the necessity ofl using wire or the like and may be quickly and easily applied or released. Y

The' feeders or hot'tops now in common use are made of re clay` and have molded on their outer faces lugs which rest on top of the ingot mold and thus limit the move-v ment of the feeder into the mold. The presy 20 Vent invention inaddition `to serving as a i 3@ which provision is made forthe necessary expansion incident to the ,pouringoperation The clamp embodies a; transversely split band to surround the feeder and a still further aim is to provide a clamp for connecting theendsof said band, said clamp embodying springA means which "acts not only to hold it in operative position, but permits separation of the. band ends under expansion of the feeder. Y f VVViththe foregoing inview, theinvention resides Vin the novel subjectv matter hereinafter described and claimed, description being accomplished by reference to the accompanying drawing.

The drawings'above briefly described illustrate the preferred form of construction and while such construction will be herein specifically explained, variations may be made within the scope of the invention as claimed. y f

B on the drawings denotes the band as'a Whole, said band being formed of any desired number of sectionsS'of any desired shape, according to the shape'J of the ingot feeder F which the band B is toV surround. lIn thel present showing, only two sections S are disclosed and they are yieldably connectedrby a connection C hereinafter described, and` the ends of the band B are releasably connected with eachother by a clamp C whose details ,70 will also be explained. Upon release of the clamp C', the connection C and any other similar connections which the device `may embody if of more than two-section construction, will act as a hinge as will be clear from 1 Fig. 4, permitting outward swinging of the sections S for application to or removal from the feeder F. Upon tightening of the clamp C', the band B is tightly lheld around the. feeder F and upon expansion of the latter incidentV to the pouring operation, portions of said connection C and clamp C vwill expand' 'to any required extent. In case the-feeder F- should crack, the band Brwill tightly hold it in shape and will not permit any portionsV thereof to fall into the ingot mold. In addiltion to performing this function, thefband B limits the insertion of the feeder F into the ingot mold M, by resting upon the upper edge of the latter, and to insure proper positioning of said band upon the feeder, any desired means may be employed. Y Pins P are here shown insertible into openings O in the feeder F, said pins being loosely connected i with the band B by chains or the like. 95 The connection C embodies two lugs 5-6 secureduto the adjacent ends of the sections SV and projecting outwardly therefrom, said lugs having openings 7 through which a Ylike 2() and the lug13.

ti'on- 17 of link 14- is preferably bifurcated the feeder F. Then too, due to the-loose# ness with which the bolt 8 is received in the openings 7, the lugs 5-6 may angle upon the bolt, allowing the entire connection C to constitute a hinge as seen in Fig. 4, when the-.clamp is lopened and closed.

The clamp C embodies two spaced hooks 12 secured tofone end of the band B, an apertured lug 13 secured to the other: end

i'- of.` this: band, a link 14, a springi15 associated with Vsaid link, and aV lever 16 fulcrnined tozsaid link and engageable with the hooks 12,. The link 14 extends across thesplit fbetween the ends of the'isections-S' and one end` of this link is outwardly bowed around thel hooks 12 as seen at 17. The other end ofthis link is in the form of a vshank 1S passingrloosely through the aperpro-l vided with a nut or other shoulder 20 spaced turel 19A of the lug 13, said shank beine' outwardly from said lug. The springVV 15 is of coiled compression form and it sur-v rounds the shank'lSrbetween the nut orrthe The bowed end porand the lever 16 is pivoted at 21 near one of itsfends, 4between the furcations of said link end, said end of the lever being provided with oppositely projecting studs 22: engageable with thehooks 12 to provide thefulcrnm about which the leveris moved, When lever lisl swung inwardly to the position shown.

in Fig. 2,V the pivot 21 is slightly beyond a straight line passing through the center of the opening 19V and the studs 22, so that'the` springfl will hold the lever in this position. Then too, this *spring yields under eX- pansion. of the feeder F and co-cperateswith Vthe spring. or springs 11 inV allowing the necessary expansion of the band B. When lever-16 is swung outwardly as in Fig. 4,Y the ends of the band are disconnected from each other and consequently said band is in readiness for quick and easy application to or removal from the'feeder F. If desired, a

Vlength of pipe or the like 23 may be slipped over the outer end of thelever 16 for operating itffrom a distant point at which-the heat is, not so intense as in immediate proximity tol the feeder and mold.

The entire band B is provided throughout its inner circumference with a ventilating channel 24 and a plurality of openings 25 extend from this channel to the exterior of the' band'. Air may flow freely through invention. ALs Vabove stated, variations may be made within the scope of the invention asV claimed, in which connection attention is again invited to the fact that the band. B

may embody any desired number of sectionsv S connected. with` each other by yieldable connections such as C. Moreover, the shape of the sections S' may vary in accordance with the shape of the feeder to which thev device is to be applied. Then too,lvari'ous changes in size, proportion, materials, etc.,

may be resorted to within the scope of the'v claimed p invention,
